I have a friend (as brilliant as he is) who recently spent a day or so recovering from a self-induced, internal drought. He was miserable.

If you’re an active person, you’ve probably experienced an imbalance between water intake and water loss at one time or another during an extended period of exercise. It’s not pleasant and greatly impacts your performance whether you’re out for long mountain bike ride or playing a hard-fought tennis match. Exercise capacity can be compromised when a person is dehydrated by as little as 2% of body weight. That’s not much.

We often focus on food sources of fuel, but fatigue during exercise may be the result of dehydration as much as from lack of nutrient intake. It takes much longer to recover from a hydration deficit than it does from a food (energy) deficit. You can eat a banana or a handful of jelly beans and feel better in minutes, but if fluid intake is compromised, it takes a lot longer to recover. If you’re feeling like a saguaro cactus—hot, parched, and moisture-deprived—it will take hours for fluids to trickle back into your blood plasma, muscles, and intracellular fluids. It’s best to make sure you’re well-hydrated to begin with and take measures to stay hydrated while active.

Sip, sip, sip.

And guess what? Food counts as hydration. At least some food does. Processed food contains no water. Raw vegetables and fruit contain quite a bit and come with a supporting cast of nutrients, including sodium, potassium, and magnesium—critical electrolytes lost through sweating.

For a detailed post on the differences in high-powered blenders, check this post from my friend Alexa at Lexie’s Kitchen. She’s the blender guru. I have a VitaMix and I love it, but there are several other blenders on the market that will also pulverize chopped beets and celery.

I’m guessing you probably stopped by hoping to find a recipe for something exciting like peanut-butter chocolate cake or frosted cinnamon rolls. Maybe a nice cheesy casserole or a chocolate Easter bunny.

Sorry.

I’ve been sidetracked lately by the dazzling microcircuitry and super-powers of the cerebellum, my favorite brain region. You might want to stick with me on this, especially if you’re curious about the many ways gluten can wreak havoc on your health and derail your Cirque du Soleil ambitions.

Here’s the deal.

Ataxia is a lack of muscular coordination and balance. It’s a loss of precise movement. The main function of the cerebellum is to evaluate how well movements initiated by motor areas of the brain are actually being carried out. It’s responsible for orchestrating muscular action in a controlled way. If the motor areas of the brain aren’t skillfully doing their jobs, the cerebellum detects the discrepancies and via a complex network of feedback signals, attempts to correct the errors.

If you want to ride a unicycle and juggle while being distracted by women in short skirts twirling around on roller skates, you better have a high-functioning cerebellum. Do you remember world-class, short track, speed skating champion, Apolo Ohno? Didn’t it make you a little nervous watching him bumping elbows with the South Koreans while taking corners at high speeds? He was practically horizontal. My gosh, how did he manage to stay upright (at least most of the time)? That kind of movement takes dynamic balance, sensory control, reflex adjustment, and incredible coordination. The cerebellum takes note of everything that’s going on with the body in space and makes instant adaptations to maintain equilibrium.

That’s if nothing is sabotaging its performance (and yours).

This under-appreciated little structure of lobes, white matter, grey matter, and other assorted goodies accounts for only 10% of the brain mass, but contains approximately half the neurons (specialized nerve cells) in the brain. That gives you an idea of how important it is. Researchers are also finding the cerebellum plays a roll in cognitive function and language. There’s a lot going on in that part of the brain.

Now throw some gluten into the mix and you might have problems with even the simplest of movements. Like walking, skipping, catching a slow-moving beach ball, or retrieving a word from the tip of your tongue. Cerebellar ataxia is one of the most common neurological manifestations of gluten intolerance.

Dr. Alessio Fasano, world-renowned celiac specialist and Italian cutie-pie (well, isn’t he?) from the University of Maryland’s Celiac Research Center says, “The gut is not like Las Vegas. What happens in the gut doesn’t stay in the gut.”

Such is the case with gluten ataxia. People with the genetic and environmental susceptibility to gluten ataxia may not even have gastrointestinal symptoms, although the problems begin when gluten hits the small intestine. Unfortunately, the potential for damage doesn’t stay there. It can also have an impact on the brain. Studies show that 60% of patients with gluten ataxia show cerebellar atrophy on MRI. One study I read suggested that prolonged exposure to gluten in people with gluten ataxia was irreversible. Obviously, the sooner the diagnosis, the better. I’m not a doctor (I’m a nutritionist taking ballet lessons), but I believe a healthy gluten-free diet of nourishing whole foods and activities that stimulate cerebellar function can do wonders for people with neurological problems and can be protective for those without.

What kind of activities?

Dance lessons, yoga, tai chi, juggling, tennis—any activity that requires balance, movement, and attention to detail. Even tossing a beach ball back and forth stimulates the movement centers of the brain. Research shows that structural changes occur in the brains of people who engage in activities that require balance and coordination—jugglers, basketball players, speed skaters, dancers. If there is evidence of architectural changes, then why not exercise your cerebellum? Nothing to lose and everything to gain.

Plus, you might have fun in the process. Latin dance lessons? Ballet?

Check out this video of cerebellar rock stars, Bob, Trish, Chip and Laura. It’s short (1:17), fun, and will give you an idea of what it’s like to have a top-notch sense of balance and coordination. This kind of skill takes a lot of dedication and practice and I bet on MRI, these folks would have a blue ribbon network of neurons guiding their movements. They’re exercising their bodies, but they’re giving their brains a workout as well.
